<p><font face="Ubuntu">Hi Donald,</font></p>
<p><font face="Ubuntu">Hi forgot last week to discuss one point. So,
I prefer add it before forget it again.</font></p>
<p><font face="Ubuntu">It concerns the management of mpls label
space.</font></p>
<p><font face="Ubuntu">Up to know, we have LDP and BGP that deal
with MPLS labels. I'm preparing Segment Routing for OSPF, and
for IS-IS. In Segment Routing, you must specify at least one
(but possibly many) Segment Routing Global Block (SRGB) that
reserved a block of labels. Once done, Segment Routing allocates
an MPLS label in the SRGB for each router in the OSPF domain and
a lable per interface outside the SRGB. The issue is that we
must be sure that a) the SRGBs are reserved for Segment Routing
and not used by an other routing protoco, b) that standard label
allocation by the different routing protocol are not overlapping
SRGB and c) that label allocation is unique i.e. a label is not
used by more than one routing protocol. I already discuss this
point with Renato last summer and re-activate this issue after a
call with peoples interested by Segment Routing that Lou
introduce for me.</font></p>
<p><font face="Ubuntu">So that, I would discuss the best way to
manage MPLS labels spaces to avoid overlapping of label. I think
about 3 scenarios:<br>
</font></p>
<p><font face="Ubuntu">1/ By means of configuration. Simple, but
report the issue to the user</font></p>
<p><font face="Ubuntu">2/ At the zebra layer. More dynamic, but need
to add extra message and code to zebra API</font></p>
<p><font face="Ubuntu">3/ At Linux Kernel. Not sure it is the right
place.</font></p>
<p><font face="Ubuntu">Regards</font></p>
